Not far from Toesca subway station is Palacio Cousino. It was a palace that featured big in Santiago's high Society in the late 18th Century when it was built for dona Isidora Goyenechea. Goyenechea is the widow of Luis Cousina who made a fortune with coal and silver mining. The neoclassical palace is decorated with furnishings and decorations imported from Europe. It's worth visiting although you have to take the 45 minute guided tour which is available in Spanish and English.
It cost me 2000 CLP (November 2007) for the guided tour
Palacio Cousiño is a beautiful mansion; it belongs to Family Cousiño, one of the richest families of Chile. This ancient building is open to the public, and there you can find furniture, finery, paintings, sculptures, of 19th century, and a beautiful architecture. The stairway, made of marble, is just amazing.
